Uppsala Universitet har utvecklat en inducerbar CRISPR-Cas9-ram för genredigering av gram-positiva bakterier som tidigare varit svåra att modifiera genetiskt. Metoden utnyttjar bakteriernas eget Cas9-system istället för externa plasmider, vilket minskar komplexiteten vid funktionell genomanalys av icke-modellbakterier. Många industriellt och ekologiskt viktiga bakterarter saknar etablerade genetiska verktyg, vilket begränsar förvärvandet av kunskaper om deras funktionella egenskaper. Forskargruppen löste denna flaskhals genom att aktivera endogena CRISPR-system, vilket öppnar för snabbare karakterisering av värdassocierade och miljöbundna gram-positiva species. För FoU-ledare inom bioproduktion, såsom fermentationsbaserad tillverkning och probiotikautveckling, tillhandahåller tekniken ett verktyg för att raskt testa genotyp-fenotyp-relationer utan att konstruera nya vektorsystem. Denna metod förkortar utvecklingstiden och minskar kostnaderna för att validera kandidatceller innan klinisk eller industriell skalning.
CD163-receptorn på makrofagers yta minskar när 7-oxysterolar triggrar celldöd — en upptäckt som kan förklara varför vissa makrofager blir skörare i aterosklerosbetad. Forskare vid Linköpings universitet exponerade THP-1-makrofager för en blandning av 7β-hydroxikolesterol och 7-ketokholesterol (2mix), två oxysterolar som ansamlas i ateromatösa lesioner. Resultatet visar dosberoendet: ju högre 2mix-exponering, desto lägre CD163-nivå på cellöverflöden. Samtidigt steg reaktiv syresspecies (ROS) och apoptosmarkörerna markant. CD163-uttrycket korrelerade omvänt med både celldöd och oxidativ stress. Studien föreslår att CD163 skyddar makrofager mot oxysterol-inducerad apoptosis. För läkemedelsföretag som utvecklar atheroskleros-terapier betyder detta att CD163-modulering kan påverka plackstabilitet. Resultat från Linköpings kliniska avdelning för obstetrik och gynekologi och institutionen för biomedicinsk och klinisk vetenskap öppnar nya målstrukturer för inflammationshämmande strategier.

Leverantörer av stamcellsterapier kan nu erbjuda en praktisk väg till förbättrad levertransplantation. Forskarteamet vid University of Karachi och Karolinska Institute visar att mesenkymala stamceller (MSC) differentierade med kvercetinbehandling återställer leverfunktion helt i djurmodeller med gallgångsbilning och fibros. Metoden bygger på en sekvensiell signalering: kvercetinbehandling hämmar först Wnt/β-cateninsignaleringen för hepatocytdifferentiering, medan rutinoch litiumklorid senare aktiverar vägen. Transplantation av kvercetinpreparerade celler normaliserade levervärden, minskade inflammation och fibros och lokaliserades framgångsrikt i leverväven. Kombinationen av flavonoider och litiumklorid — redan kliniskt använt läkemedel — erbjuder en skalbar ex vivo-strategi utan nya farmakologiska utvecklingskostnader. För bolag inom cellterapi och regenerativ medicin öppnar detta möjlighet att adressera fibrotiska leversjukdomar inom två till tre år.
